Context Harvester от Rishap Gandhi

Context Harvester lets developers collect text from multiple browser tabs and export as structured, token-aware prompts for AI assistants like ChatGPT, Claude, and Gemini.

Features:
• Right-click or Alt+C to capture selected text with source attribution
• Real-time token counter with model selector (GPT-4 128k, Claude 200k, Gemini 1M)
• Auto-detects content type: code, docs, error, discussion, reference
• Drag-to-reorder snippets for optimal prompt structure
• Export as Markdown, structured XML prompt, or JSON
• All data stays local — zero network calls, no account needed
